Liquid crystal display apparatus and method for manufacturing liquid crystal display apparatus

Abstract

A liquid crystal display apparatus is provided with an array substrate including a first substrate, a switching element formed on the first substrate, an interlayer insulating film formed so as to cover the switching element, a pixel electrode formed on the interlayer insulating film and connected to the switching element via a contact hole formed in the interlayer insulating film, an alignment film formed so as to cover the pixel electrode, and a spacer formed under the alignment film. A flattening layer made with the same material as that of the spacer is arranged between the pixel electrode and the alignment film within a region corresponding to the contact hole.

What is claimed is:  
     
       1. A liquid crystal display apparatus comprising: 
       an array substrate including a first substrate, a switching element formed on the first substrate, an interlayer insulating film formed so as to cover the switching element, a pixel electrode formed on the interlayer insulating film and connected to the switching element via a contact hole formed in the interlayer insulating film, an alignment film formed so as to cover the pixel electrode, and a spacer formed under the alignment film;  
       a counter substrate arranged so as to oppose the array substrate; and  
       liquid crystal composition arranged between the array substrate and the counter substrate,  
       wherein a flattening layer made with the same material as that of the spacer is arranged between the pixel electrode and the alignment film within a region corresponding to the contact hole.  
     
     
       2. A liquid crystal display apparatus according to  claim 1 , wherein the flattening layer is made of resin. 
     
     
       3. A liquid crystal display apparatus according to  claim 2 , wherein the flattening layer has a black color. 
     
     
       4. A liquid crystal display apparatus according to  claim 1 , wherein the interlayer insulating film is a color filter. 
     
     
       5. A method for manufacturing a liquid crystal apparatus where a liquid crystal layer is sandwiched between a first substrate and a second substrate, comprising the steps of: 
       forming a switching element on the first substrate;  
       forming an interlayer insulating film having a contact hole corresponding to one portion of the switching element and covering the switching element;  
       forming a pixel electrode connected to the switching element via the contact hole on the interlayer insulating film;  
       forming a spacer and simultaneously forming a flattening layer within a region corresponding to the contact hole;  
       forming an alignment film after formation of the flattening layer; and  
       performing a rubbing process on the alignment film.
